ARS template (tool) record - filename is: Harvest Tool (hand remove yield and residue).oprn
This operation record is designed to represent harvesting operations that
remove the specified "yield" of a crop without cutting the crop stalks.
However, one may remove the "residue" also as part of this operation, e.g.
hand harvesting corn for grain and also removing the entire stalk for cattle fodder
as well. This record is constructed to allow only the "yield" to be reported as the grain
harvested and not the additional "stalk" biomass also removed.
This harvesting operation record defaults to removing all the reproductive component of a crop
(typically this is specified as the "yield" component in the crop record) and to kill the crop.
This would be acceptable as defined for representing hand harvesting of corn for example.
However, it may not be acceptable for a crop that is "hand picked" several times
during the year (like peas or beans). The default parameter values need to be
changed to meet this type of harvest operation requirements. Likewise for a harvest
operation which woud remove some of the leaves instead of a "grain" yield, such as
harvesting of tobacco leaves (yet this is the template that will often be used for developing
such "leaf harvesting" operations).
See the "Detailed info regarding this operation record:" section for more specific
information regarding the use of non-default process parameter values for
this harvest operation template.

Detailed info regarding this operation record:
The default "Kill or Defoliate Growing Crop" parameter is set to kill all crops.
If one doesn't want the operation to kill the crop or only annuals, then they need
to change this value. Examples might be where multiple harvest operations
are necessary to remove the "yield" such as hand picking peas or beans.
Also, the crop plant component that is harvested can be changed to be something
other than the reproductive component (grain or fruit). For example, a fraction of the
leaves only could be specified, leaving the rest of the crop alone, e.g. harvesting of
tobacco leaves.
If a harvest operation is expected to "cut" the crop to a prescribed height (or depth
from the top of the canopy), then one of the "cut and remove" harvest templates should
probably be used instead of this one.
